They should also require a warrant at least, especially for any data sharing. With "they can only be accessed by law enforcement", we've already had plenty of police harassing their exes. If they couldn't convince a judge to let them use the camera, there's really no hope of the case going anywhere.

I'd argue worse is "we know exactly who did it and we're not going to do anything about it (but we would do something if you try to do something about it yourself)".
